2. A galvanic cell positive and negative elements, and a depeiarieing eiass centaining clerk brawn mengenie k3 erase. K I

A galvamc cell comprising positive zine element, a negative earbom. elememfi, and degolerizing for the negeive carbon element consisting of an iii ariete mixture of brexm geed-eendmmmg menganic. hydrate carbo L' .c-i-galve-nic cell eompzising a positive zine elemeni, en'egative carbon element, and a. depolarizing mass for the negative carbon ducting mangzmic hydrate.

In testimeny whereo'f I. havehereunto set. my hand in presence of two witnesses.
